Hi all! I have been reading alot of post about Streak's low quality sound output, and I'am experiencing it too, when I plug in my head phones there is no hissing sound, but when I click play or receive a call hissing sound starts and does not end till audio output end.
There is alot of post from people that have the same issue, I will Quote them below. I'm posting this because everyone that has posted this issue has been "overrun" with other people posts that they do not have that background noise.
I just want to expand on this problem, could it be Android version, or perhaps different hardware? Any suggestion is welcome.

Hi,
Personally I find that whatever I use as earphones, I have a hard time accepting the noise level on the streak. When playing music at a medium volume, the noise is really very very present.
I suppose there is no work around is there? Doesn't this bother you for serious listening?

The sound quality is absolutely abhorrent in comparison to the Galaxy SII or any other smartphone I've ever used, including the HD2, Vibrant, several Nokia devices, etc.
There is a constant and definitely audible signal noise in the Streak that really bugged me. As a recording engineer, I can definitely hear the difference between the audio systems on the two devices. When the playback system kicks in, you can literally hear the hiss in the background. When the playback stops, the hiss vanishes. Upon further investigation, it seems that this is a known issue that found its way into several reviews. If I hadn't heard it for myself, I'd have not believed how terrible it actually sounded, and frankly, it's SO bad that I find it inexcusable on such a high-end device.
I sold my iPod and bought a larger MicroSD to use my phone as my main portable media device, and the Streak really let me down.

If it's boosted, wouldn't that cause more noise since noise will also be boosted?
I'm having the same problem. Hissing noise in the background. I also got mine couple days ago. I bought it when it was $200 unlocked from dell.
I'm on stock 347. I should have tested the earphone when I had 351.
It makes the hissing noise in music, internet radio, wherever sound is being played. It has a constant level of hiss noise even if I raise the music volume or reduce it to minimum.

I believe it's the hardware. Doesn't matter what OS level you're running (I've experienced it on 2.1, 2.2, 2.3)
I've actually found it to be more tolerable on the Dell oem headphones when compared to my nice headphones (etymotic research er6i)

I hope its OS because some don't have this issue, maybe MIUI 2.3.2 Rom wont have this problem (when they fix the problem with headphones not being recognized).
And yes, on Dell oem headphones it is less noticable but compared to 50-100$ better headphones, Dell's are low quality, although they are one of the best in box headphones that comes with device.
I have some basic knowledge in Java and C. Could anyone point in the right direction so I can try to edit/tweak some setting of audio output. Any info would be appreciated.
It's also noticible on the S7 and venue. At least on the S7 you can only really notice it in a room that's completely silent, but at least for that i'm talking about the external speakers.
All I can say is that it's pretty much not noticible for me as long as it's not silence/very low volume music. At least for me it's very easy to drown out the hiss by raising the volume as it does not/minimally scales with the volume.
Keep in mind that the speakers/headset jack simply do not recieve power when not in use, the hiss on them could be part of the inherent design of it. It might be noise after the DAC as it doesnt scale anywhere near 1:1 with the audio. But I'm just blindly guessing

Did they came up with any fix for S7 and Venue?
In DSC rom update there is a line that says:
I'm using MIUI so can someone confirm if this changes anything?

The V has pretty much no perceptable hiss, and I believe the V and S5 share the same audio drivers (dont quote me on this), it might merely be a hardware issue on the S5.
I cant really say much about the S7's headset out, as it's rather unwieldly to use that way.
Also I'm very sure that it ISNT dependant on volume, like previously mentioned unless your current headset is loud to begin with, just turn up the volume and it drowns out nicely.
But yes it will be noticable on the quiet parts of music or during track changes.
tl;dr: turn up volume, V's got a cleaner output
Equipment tested on:
S5: CM7.2
S7: SD7-r9 (514-xx)
V: SD4-250 (408)
headset: iphone in ear headphones
I think its just the poor SNR ratio of the streak, its only -79db or something, its very poor.

Makes me sad
I've been a iphone user for a long time. but oh well now i have a galaxy note 2...
anyways, the problem is that when im using my earphones i hear this white noise whenever I text or play / stop music.
I've done some research and i found that the issue can be resolved by reducing headphone amplifier using Stweaks or Exteaks if my phone is
rooted.
my question is......... is there anyway to reduce the headphone amplfier value without rooting my phone?
If you have any other solutions please let me know! :laugh:
You could try using headphones that are harder to drive. It may work. You will however loose volume.
Hey Guys.
I'm creating this thread since I did not find any other old thread about this issue.
When a song or any audio output is done through the Redmi Note 3's Speaker or when it is connected to a Amplifier like a car stereo then there's an Awkward ssssss or Hissing sound.
I've used Two Different models of the Redmi Note 3 thanks to Amazon and both of them have this.
It has a very very low possibility of hardware error.
When a song is played at 1/7 of the total volume, put your ear near the device speaker and listen carefully. You might notice a weird hissing sound. It goes away when there is deep and strong bass but is there lots of times.
Using an amplifier it is most noticeable at lower volumes.
I hope you people understand.
Respond ASAP!

I too faced that situation... But in my case..
The 3.5 mm jack is broken..
I mean.. There's no problem with the phone.. But in sound system I use...
Have you checked this problem with other speakers ...??

Hey,
I actually have noticed this when I played music in my Car and also from the phone's Speaker itself!
Both when the volume is Very Low....
I know it's not a problem with my piece because I've checked with many RN3 Users and same issue is being detected there too.
My RN3 is new and in superb Condition and so are the other Appliances like the Car Stereo I used.
Even then this Hiss sound is there.
I wonder of its a problem with the Chipset altogether since there isn't a sound/music chip in it...
I hope it's a software issue and gets resolved fast...
When recording sound from the speaker output yes the sound is levied towards the high end, this is probably what causes the hissing sound in your amplifier since it can't properly amplify that freq or something along those lines, I'm not too sure since I'm no sound engineer but that's just my 50 cent.
Edit
Dumb me, your amplifier is probably a 3.5mm headphone Jack right? If so then there shouldn't be this issue and my above statement wouldn't apply ;-;
I noticed this when using Viper Audio. There was a small but noticeable hissing in the left earphone. It went away when I turned off playback gain control.
Maybe check if any equalisers or headphone effects are on and turn them off?

I had checked everything possible. I even did now.
No part of the settings, equalizer, audio effects could fix it....
And where's the option you're talking about for playback gain control? I'm still unrooted with a locked bootloader on MIUI V7.2.3.0LHOMIDA
The sound is there in both speakers in my case. I'm not using anything other than the stock music application and some great songs on an amplifier I.e. Cars stereo
Anybody has got the solution? I am also facing same issue ??

Not till now.
I've bought this Bluetooth audio adaptor that serves my purpose in the car.
Funnily nobody at Mi noticed this.
I'll do a bug report highlighting this issue.
Everyone else plase do too!

I have also dropped them a mail. Will also report bug. Thank you for your solution but I'll probably have to wait as my car system does not support Bluetooth.

Even mine didn't support Bluetooth.
If your Stereo supports USB and Aux in, you can also go for the adapter since it only needs those two.
USB for Power and Aux In for the Music.

I had a similar problem. Whenever I connected my headphones to my Redmi Note 3, there would be a weird hissing noise at low volumes especially. At higher volumes, it would reduce. I found a fix to this on Reddit, but you need to be rooted.
https://m.reddit.com/r/Xiaomi/comme..._3_pro/?utm_source=mweb_redirect&compact=true
Looks like a legacy. We are well into 2017 and the issue still exists. I bought my RN3 a couple of weeks ago and noticed the hissing on the third day of use. I just have been ignoring it. After all, it's a Chinese phone. I bought it and I have to live with it.
Good afternoon! The solution for problems with Redmi Note 3 and AUX is the following (solves the problem of correct detection and noise during playback): it is necessary to solder or otherwise connect resistors with a rating of 10 ohms between the common "0" wire and the left and right channel wires (I did 17 Ohm , did 10 ohms - both options work).
After you make this cable, the sequence of actions is as follows: the cable is first inserted into the smartphone, wait for the icon to appear with the headphones, and then insert into the AUX-input of the radio or audio system.
Hey guys!
So i just bought a P20 lite, switched from Iphone 6 to this new phone and I love it.
But i figured out the headphones volume (with the same headphones) is just really really really low, i tought something is wrong with my Phone, but i've tried out a few in the Retail Store, and they are the same low volume as mine. Is there any way to make it louder without Rooting? I saw a few videos on YouTube that you can go into an EngineeringMode, but it only works with the MediaTek phones.
Any ideas?

Don't call me names, but have you tried the obvious of choosing "Yes" when a prompt saying "Raise volume above..." When increasing the sound via volume buttons?

Yeah of course, it seems to be a software limitation i think. But its kinda stupid.
Where did you buy the phone?
I've been using mine and the sound outputs perfectly, even with the headphones provided. I'm able to listen to music while commuting and hearing properly while driving with my windows down

Well i bought at UPC Hungary (ISP) so its coming from a verified supplier, with Huawei warranty, now i went to huawei to fix my phone, becuase i bought a BT headphone, and it was lagging while listening to music (Music was stoping for 1-2 sec, then it was playing fast forward for a few) so right now im just waiting

Hi,
I have the same "issue" with mine. Also switched from i6 and I've used OnePlus 3T as well and both of them were louder and the quality was much better than P20 lite.
Do you have any solution? (bought it from Vodafone Hungary)
You are comparing a mid-range phone with an apple flagship phone definitely the p20 lite will be a bit lower than the iphone even with high end earphones its not gonna sound like a flagship one
it has software limitation...i can increase sound by 200 and maybe 300% (did it in P8) but my phone not rooted, and i listing music through bt headsets

Iphone 6 is not even close to a flagship phone, really old, so the comparison is i think not one sided.
I to was not happy with the volume on the P20 lite, but as pointed out, it is at a Perfect Pitch to enable you to Still listen to what is going on around you(well done Huawei), which is a very good safety precaution. The quality of the sound is very good, I can only put it down to the type and make of headphones you are using, travelling on the London tube where there is a lot of noise I prefer the Denon exercise freak in-ear (wireless), these headphones also have their own volume that block out everything, including the tube, perfect for the surroundings. But for normal everyday use I prefer wired overhead B&O h6 headphones for the quality, and being able to hear surrounding sounds is for me a must(safety is a hi feature in my life). Try Currys PC World they have a good range of headphones that are set up for testing and I'm sure you will find a set that meet your needs.
Hi guys, I was a member here back in the windows mobile days, I figure this is a good place to ask some questions.
I have a LG v60 and while using Sony MDR-7506 headphones I clearly notice a distortion and noise creeping in at some point when I move the volume slider. It's only noticable while the HI-FI Quad DAC is on and mostly on the left ear. It's very easy to hear with MDr-7506 as they are very bright and reveil top end easy. I'm wondering if anyone else has noticed anything like this, or perhaps I'm having a hardware problem. I've tried UUAP with bit perfect and the noise/distortion is even more clear with that app. I can duplicate the issue with an audio signal generator playing a frequency. The distortion noise is not there on low volume and not aperant on high volume, it's somewhe in the middle but very obvious and audible to me with Sony MDR 7506. Also noticable with 32ohm beyerdynamics 770. Perhaps hardware problem or quad DAC plus low impedance headphones matching issue, I'm confused and hoping some of you might be able to help. Thank you in advance
I haven't noticed this with any of my headphones. I usually use a pair of Focal Clear (55 ohm). I'm no expert but I'd guess it's a hardware issue. If you have time you can try flashing older (or newer) firmwares to see if that has anything to do with it (I'm on an updated T-Mobile variant).

Thank you for replying, your Focal Clear is just above the 50ohm trigger for the Quad Dac. I bet they sound great with the V60 dac. I'm having issues with some of my 32ohm headphones not being amped properly and having to trick the DAC using an extension cable.
I wasn't aware of being able to flash older firmware on the v60, I'm on a Bell Canada model LM-V600TM and currently running V600TM10q firmware. I used the LG Bridge software to update it once since I got it. There's an update available so I'll try that next.
I suspect that's it's something related to the Quad DAC as it's only there when it's enabled, with certain headphones it's painfully obvious. Its right at or just above the volume I prefer to listen at. The MDR-7506 and dt770 250ohm both make it possible to really hear the noise floor on most recordings, exaggerated high frequencies could be the reason for that.
I would appreciate any links or info on downgrading the North American V60. I love this device, it's my first Android and I didn't know that the bootloader was locked or crippled when I got the V60. I spent many years in the jailbreaking iOS community. Apple removing the headphone jack was the main reason I gave up iPhones. It's good to hear that it's not all v60s that act this way
I found a thread on here that seems to be about the same issue, I posted here before I found it, hopefully it helps shed light on this. There's ppl from Germany that report the same noise problems so it's not just me.
